I need to sync windows time of Server (172.16.4.21)with a external GPS (188.8.131.52). I am able to ping gps from server. I added gps IP in Internet Time server and when I click on Update now it's showing Time is susuccessfully synchronised with 184.108.40.206.
I changed the update time in registry to 15 min. But sometimes in the Internet Time (Date and Time Settings) it is showing peer not reachable. And I have noticed even though its showing successfully synchronised there is an actual difference of about 2 min.
I have added Sntp server address as 172.16.4.21 in one controller and it's my clock master.
How to check the Synchronisation of server to the gps clock?
Note: I tried adding 220.127.116.11 as my Controller Sntp server address, even though I added Default gateway,enabled UDP 123 Sntp protocol in firewall. In clock sync (cbm) it's showing No Sync. Thats why am trying to sync the server with the GPS and Controller with the server.
